Plimmerton Flood Response Project

Plimmerton residents and businesses have faced a number of significant flooding events in recent years.

Both the Plimmerton West (Hongoeka Marae and Karehana Park) area and the Taupo Stream catchment around James Street/State Highway 1 have been impacted.

Following the most recent flood event in November 2020 Porirua City Council and Wellington Water have set up a project to respond to community concerns and to investigate a range of solutions.

Catchment Studies

Wellington Water (WWL) and Porirua City Council (PCC) have kicked off an investigation study of stormwater management options to reduce flooding. We plan to undertake three Catchment Study investigations in the coming year.

Karehana Bay catchment Study is underway and the Project Plan which describes the study is linked here.

Starting in July 2020 the Catchment Studies for Hongoeka and James St/Taupo Stream will get underway.


While the Catchment Study investigations are taking place, we are committed to maintaining the current stormwater system as best we can. The current system is designed to manage a 1 in 10-year flood event, and becomes overwhelmed during short, intense periods of rain. When it’s high tide the system struggles even more, as water at the bottom of the catchment is unable to get out to sea.

Wellington water, Porirua City Parks Team, NZTA and Downers all have maintenance responsibilities in the Plimmerton area. This part of the project aims to:

  • Ensure a joined-up maintenance plan and schedule
  • Share this maintenance plan and schedule with the community
  • Provide evidence that the maintenance is occurring as agreed in the maintenance plan.

To provide information about what stormwater assets we maintain and how often, we've developed a new GIS map which details the maintenance schedule for the various assets in the Karehana Park and James Street catchments. The map is a work in progress, so we'd love your feedback. Take a look

Community Engagement

Following the flood in November 2020 the Plimmerton Flood Action Group established themselves as a touch point for the Community. Council are also working closely with this group.

Plimmerton Flood Action Group and on Facebook, search “Plimmerton Flood Action”

A Working Group, representing the community, has also been established to provide direct feedback to Council and Wellington Water as we work through the Karehana Catchment Study investigation
